[0001] The present invention consists in an assembly for rolling blinds that includes a coiler device for blinds foreseen for being connected to the ends of an axis of a winding-on drum; that it involves a support portion connected with retention by interlocking of at least a defined elastic element in a support element for its fixation to a ceiling or in a wall, so that this support portion extends radially with respect to the axis of the drum and involves a cavity with an access opening, and because the support element incorporates two fins, with elastic deformation and fits to pressure within the mentioned cavity capable of showing through two windows one in front of the other of the mentioned cavity.

BACKGROUNDS OF THE INVENTION

[0002] It is known in the state of the art different fixation systems, by clips, of blind elements.

[0003] The Spanish utility model n° 9600893 (1033780U) “Fixation device for assembly of drawers of blinds”, in the name of Persianas Persax, S.A., it is specially thought for the connection or the mutual fixation between front ends and profiles or constituent plates of the longitudinal walls, and it uses a clipping system, in correspondence with each point of fixation foreseen between the front end and the plate, which it has to incorporate a first tongue-piece to which the clip is fitted and later the clip is fitted together in the profile or plate.

[0004] In U.S. Pat. No. 5,709,258, of Advanced Design Group, LLC, it is foreseen clipping systems in the blind cap for fixing the elevator system of the rope.

[0005] Also it is known the clipping system in the U.S. Pat. No. 5,273,096 where a clip is used to fix a tubular member and the rope or cable for going up and going down the blind.

[0006] All these inventions can not give a solution to the same problem, once you have the blind guide, sometimes with the curtains hanging, how you can take it down from the ceiling or the wall or hang it again without any problems with belts, cables, guides.

BRIEF DESCRIPTION OF THE APPLICATION

[0007] This application has as its objective to facilitate the task of positioning of blinds by means of a simple installation of the same ones, making its assembly easy and its later extraction in the case it was necessary.

[0008] One of the great problems for the positioning of blinds consisted in that the support that held the blind, when fixing it to a fixed element like a wall or ceiling, or it has to be fitted together to the blind coiler, which it made difficult the exact positioning of the same one as a consequence of the weight of this last element, or said support was a square to which once it is fixed to the wall the blind coiler had to assemble, but it did not make that the mentioned problems disappear.

[0009] The inventor has created a assembly that it facilitates the positioning of the support by its reduced dimensions and weight, and on the other hand the coiler does not have to assemble, because simply introducing the support within a cavity associated to this coiler element, through a mechanism similar to a clip, the support is blocked into the cavity and coiler element is held in that way.

[0010] Moreover, if it was necessary to strip the mentioned coiler element, simply pressing the fins existing in the same support and the coiler element is being free by its own weight.

[0011] A protuberance in the support has been foreseen, that once it is introduced into the cavity, it is located into a second cavity, which it exists between two walls inside the first cavity, with the technical characteristic to support the weight of the coiler element, when the effort of the assembly must be horizontal and nonvertical type.

[0012] Another one of the advantages of this system is that it allows to reduce the dimensions and weight of means of driving of the coiler element.

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] With the purpose to facilitate the explanation a sheet of drawings is attached to the present description in which it has been shown a practical embodiment, which it is mentioned only for purpose of example, non limitative of the scope of the present invention.

[0014] In these sheet of drawings:

[0015]FIG. 1 shows a frontal sight of the assembly for rolling blinds, with a section cut of the fixation of a support element in the ceiling, without being assembled in the ceiling.

[0016]FIG. 2 illustrates a lateral sight of the assembly, without being assembled in the ceiling.

[0017]FIG. 3 consists of a frontal partial sight of the assembly, already assembled in the ceiling, with a section cut that allows the support element to be seen.

[0018]FIG. 4 represents a lateral partial sight of the assembly, already assembled in the ceiling, with a section cut that allows the above mentioned support element.

CONCRETE EMBODIMENT OF THE PRESENT INVENTION

[0019]FIG. 1 is a sight of the assembly which it includes a first piece composed by support elements (3), a portion (15) that joins two small arms (16) of the mentioned support element (3), with a protuberance (14) in the centre of the mentioned portion (15), fins (9) at the end of each small arm (16), a hole (5) in said portion (15), in order to allow to make pass a screw (11) to fix the referred portion (15) to a wall or ceiling (4); and a second piece which it incorporates a support portion (6), which it includes a winding-on drum (2) with an axis (1), windows (10) which they belong to a cavity (7) located inside the mentioned support portion (6), in whose inner part there are also two walls (13) that define a cavity (12).

[0020] The referred first piece that it includes the support element (3), with the fin (9), fixed to the ceiling (4) and mentioned the second piece that includes the winding-on drum (2) with its axis (1), the support portion (6) and the window (10) are illustrated in FIG. 2.

[0021]FIG. 3 determines the mentioned assembly once the referred support element (3), properly fixed to the ceiling (4), has been introduced into the cavity (7), located inside the mentioned support portion (6), with the two fins (9) partially in the outside of the mentioned support portion (6), through the previously indicated windows, being possible to realise also the two walls (13) that define the cavity (12) for introduction of the protuberance (14).

[0022] In FIG. 4 it can be observed the way of fixation of the assembly, object to the present invention, in the ceiling (4), through the screw (11), which it crosses the hole (5) located in the portion (15).

[0023] In that way, in a first phase, that it is developed all over the first piece, the support element (3) is fixed through the portion (15) to the ceiling (4) or a wall, through a screw (11) that it crosses said portion (15) through a hole (5), which it was been made in it for such effect.

[0024] The second piece is approached to the first piece, in such a way that the first piece is introduced within the first cavity (7), belonging to the second piece, being necessary for it to press on the two fins (9), to allow the entrance of mentioned first piece within second.

[0025] Once the first piece is within the second piece, the resulting position is the one as follows: the fins (9) are partially on the outside through the windows (10), fixing and blocking that the first and second pieces are separated by action of the gravity, moreover introducing the protuberance (14) in the cavity (12), located this last one between the walls (13).

[0026] In order to separate the two pieces, it is only necessary to press into the inner part both fins (9) (9) in such a way that no longer they can not exert fixation and the own gravity separates the two pieces.

[0027] The protuberance (14) is significantly relevant in the case that the fixation of the portion (15) is made in a wall and not in the ceiling, so the assembly is located perpendicularly to the previously explained position, in such a way that this protuberance facilitates that the assembly remains firmly and raised in the mentioned position, due to the pressure that it makes to the walls (13).
